vision of a shutter of this character, wherein theslats or louvers are preferably made from wood while the end and intermediate cross connecting pieces are made from metal, the slats or louvers being releasably held in slotted channeled metal strips detachably fastened to the side members which latter are of wood and inthis fashion when the shutter requires repairs the same can be made with dispatch, particularly Where the wood parts become worn or rotted so that the shutter need not be discarded in its entirety.

Another object of the invention is the provision of a shutter of this character, wherein the same is composed partly of wood'and partly of metal thereby increasing the life of such shutter and by the assembly of the parts thereof repairs can be made or new parts substituted without the requirement of skilled labor for sodoing.

A further object of the invention is the provision of a shutter of this character, which is simple in its construction, readily and easily assembled, susceptible of being knockedv down, strong, durable, and inexpensive to manufacture.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying, drawing, which discloses the preferred embodiment of the invention and pointed out in .the claim hereunto appended.

In the accompanying drawing: 7 v

Figure 1 is an elevation of ashutter constructed in accordance with the invention.

Figure 2 is a sectional view on the line 22 of Figure 1 looking in the direction of the arrows.

Figure 3 is a sectional view on the line 33 of Figure 1 looking in the direction of the arrows.

Figure 4 is a perspective view of the bottom end cross connecting piece of the shutter.

Figure 5 is a fragmentary perspective view showing in detail one of the louvers or slats fitted with the slotted channeled strip therefor.

Similar reference characters indicate corresponding parts throughout the several views in the drawing. 50 Referring to the drawing in detail, the shutter designated generally at A for a window and constituting the present invention comprises spaced longitudinally disposed sidev rails I0, these being preferably made from wood and are of a length 55 corresponding to the length of the window to which is to be fitted the shutter A. At the inner edges ofthese rails III are detachably fitted chan: neled strips II preferably of substantially U form in cross section, each having the outturned lat 'terally extending side edge flanges I2 accommodating at intervals fasteners I3 which secure the said strips II to the rails In at the inner longer edges thereof. outer, upper and lower and intermediate cross connecting members 13, C and D, respectively,- which are separably joined to the rails Ill and are preferably made from sheet metal.

The strips I I are formed with spaced diagonally disposed elongated slots It accommodating louvers or slats I5 preferably made from wood. The louvers or slats I5 snugly fit the slots I4, which are located centrally in the strips I I.

The outer upper member B is formed from a metal sheet blank cut and bent to provide an intermediate diagonally disposed web I6 with reversely disposed horizontally arranged upper and lower ledges I1 and I8, respectively, which at opposite ends are formed with turned ears I9 at right angles thereto and these receive fasteners 20 for engagement in the rails Ill. The web I6 at opposite ends thereof has cut and reversely bent therefrom the triangular portions 2! provided with attaching ears 22 accommodating fasteners 23 for engagement in said rails I 0, the ears being disposed in overlapping relation to opposite front and rear faces of said rails. The pieces C and Din the construction thereof are similar to the piece B and are separably fastened with the rails As has been stated, it is preferable that the rails Ill be made from wood and also the louvers or slats I5 similarly made from wood while the strips II and pieces B, C and D are preferably made from sheet metal, thesebeing separably fastened to the rails It so that the shutter A may be readily knocked down when the occasion requires for replacing any worn or rotted parts These strips are located between thereof, that is, should the rails l0 become unfit for use or the louvers or slats I5 become unfit for further use. The separation of the shutter for the knocking down of the same can be had by unskilled labor.

What is claimed is: A shutter of the kind described comprising spaced longitudinally disposed parallel rails and outer and. intermediate cross connecting members between the said rails and each formed from a blank of sheet material bent to provide an intermediate diagonally disposed web with reversely arranged horizontal upper and lower ledges having inturned cars at opposite ends of the latter at right angles thereto for separable fastening to said rails, and reversely bent triangular portions at opposite ends of the webs with attaching ears overlapping said railsat opposite sides thereof and separably secured thereto.
